Stability Analysis of Unsteady Hybrid Nanofluid Flow Past a Permeable Stretching/Shrinking Cylinder

The study of boundary layer flow has gained considerable interest owing to its extensive engineering applications. Thus, this numerical aims investigate the stability analysis unsteady in hybrid Al2O3-Cu/H2O nanofluid past a shrinking permeable cylinder. impacts suction and unsteadiness parameters are considered study. partial differential equations converted into system nonlinear ordinary by selecting suitable similarity transformation solved using bvp4c code MATLAB program. findings revealed that existence dual solutions is visible. skin friction coefficient local Nusselt numbers increase with inclusion parameter. presence parameter actively promotes heat transfer degradation on Stability indicates stable physically realizable solution appeared first solution, whereas second unstable.
